Definitions
- the invention provides a microfluidic reaction apparatus for trapping one or more particles of predetermined nominal size or range of sizes, comprising a flow inlet and a reaction zone having an enlarged cross-sectional area in comparison to said flow inlet, said reaction zone comprising a filter means having a plurality of holes defined therein, the holes being smaller than said nominal size or range of sizes and arranged so as to trap said particles while a fluid flows from the flow inlet through the filter means.
- Fig. lb shows a filter arrangement in accordance with the invention.
- the fluid inlet channel 2 opens into a zone 2a of enlarged cross section, compared to the inlet channel, in which a filter 4' is disposed laterally across it.
- a filter 4' is disposed laterally across it.
- a greater number of holes is provided than the arrangement of Fig. la. This significantly reduces the tendency for the filter 4' to clog in comparison with Fig. la, and results in more homogeneous flow characteristics over it.
